This worked:
$("#theSelectId").prepend("<option value='' selected='selected'></option>");Firebug Output:
<select id="theSelectId"> <option selected="selected" value=""/> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="mercedes">Mercedes</option> <option value="audi">Audi</option> </select>You could also use
.prependToif you wanted to reverse the order:$("<option>", { value: '', selected: true }).prependTo("#theSelectId");讨论(0)
